> Key: FLINK-28823
> URL: https://issues.apache.org/jira/browse/FLINK-28823
> Project: Flink
> Issue Type: Sub-task
> Components: Runtime / Network
> Affects Versions: 1.16.0
> Reporter: Yuxin Tan
> Assignee: Yuxin Tan
> Priority: Major
> Labels: pull-request-available
>
> The num of the max requested buffers in SortMergeResultPartitionReadScheduler
> is determined by the num of subpartitions, which may be insufficient in some
> scenarios, such as speculative execution and partition reuse.
> Therefore, we should increase the max requested buffers to make full use of
> available memory when TM memory is sufficient.
